Description: Taza
        =====
        
        Taza is a Python library with a set of abstractions over Tacyt that provides an OO layer over the query language.
        
        ### Instalation
        
        Install via pip
        
            pip install taza
        	
        The libraries for tacyt are vendored inside taza, this is because the Tacyt python client is not distributed using pip.
        	
        ### Usage
        
        The library has currently two main components, the wrapper for the API and the query abstractions.
        
        To use the API wrapper you must instantiate a `TazaClient` class.
        
        ```python
        from taza.tacyt.TacytApp import TacytApp
        from taza import TazaClient
        
        app = TacytApp(APP_ID, SECREY_KEY)
        client = TazaClient(app)
        ```
        
        Clients can also be instantiated with a factory method that wraps the TacytApp class. Removing the need of importing Tacyt to the current script.
        
        ```python
        from taza import TazaClient
        
        client = TazaClient.from_credentials(APP_ID, SECRET_KEY)
        ```
        
        #### Querying tacyt
        
        You can send queries to tacyt for searching apps throught the `search_apps_with_query` method. This method will handle pagination automatically. This method returns a generators, so no query is actually made until the data is collected.
        
        For example, let's get the SHA256 hash of the apk of whatsapp.
        
        ```python
        from taza import TazaClient
        
        client = TazaClient.from_credentials(APP_ID, SECRET_KEY)
        
        query = "packageName:com.whatsapp AND origin:GooglePlay"
        fields = ["sha256"]
        
        apps = client.search_apps_with_query(query, fields) # No actual connection to Tacyt done here.
        
        for app in apps: # Now the generator starts yielding and therefore connecting to Tacyt.
        	print(app)
        ```
        
        #### Query language abstraction
        
        The queries are send as a string to Tacyt, this means that the queries must be managed as strings, which sometimes can get messy. Taza has an OO abstraction that allows to write queries in Python.
        
        First, each predicate can he specified with the `cond` class. There is also `packageName` and `fromGooglePlay` as shorthands for that queries.
        
        ```python
        from taza.query import cond, packageName, fromGooglePlay
        
        q1 = cond('packageName', 'com.company.awesome_app')
        q2 = packageName('com.company.awesome_app')
        
        str(q1) # => "packageName:com.company.awesome_app"
        str(q2) # => "packageName:com.company.awesome_app"
        str(fromGooglePlay) => "origin:GooglePlay"
        
        assert str(q1) == str(q2)
        ```
        
        The predicates can be combined with AND, OR and NOT operators.
        
        ```python
        from taza.query import cond, packageName, fromGooglePlay
        
        q1 = cond('packageName', 'com.company.awesome_app')
        q2 = packageName('com.company.awesome_app')
        
        str(q1 & fromGooglePlay) # => "packageName:com.company.awesome_app AND origin:GooglePlay"
        str(q2 | -fromGooglePlay) # => "packageName:com.company.awesome_app OR -origin:GooglePlay"
        ```
        
        Bear in mind that Tacyt only allows up to 40 predicates per query.
        
        If you need to agreggate several predicates under the same operator, you can use the `or_many` and `and_many` functions. They are usefull is you need to define the query programatically under a set of elements.
        
        ```python
        from taza.query import cond, packageName, fromGooglePlay
        
        q1 = packageName("app1")
        q2 = packageName("app2")
        q3 = packageName("app3")
        
        assert or_many(q1, q2, q3) == (q1 | q2 | q3)
        
        qs = [fromGooglePlay, cond('versionCode', '42'), packageName('my.another.app')]
        assert and_many(*qs) == (fromGooglePlay & cond('versionCode', '42') & packageName('my.another.app'))
        ```
        
        These queries are sent to the `search_apps_with_query` method in the same way that string based queries are sent. The whatsapp example could be written as such.
        
        ```python
        from taza import TazaClient
        form taza.query importy packageName, fromGooglePlay
        
        client = TazaClient.from_credentials(APP_ID, SECRET_KEY)
        
        query = packageName('com.whatsapp') & fromGooglePlay
        fields = ["sha256"]
        
        apps = client.search_apps_with_query(query, fields) # No actual connection to Tacyt done here.
        
        for app in apps: # Now the generator starts yielding and therefore connecting to Tacyt.
        	print(app)
        ```
