Library detection

##Input The libraries detector would accept the absolute path of Arduino project folder as input. ##Output The libraries detector returns a list of libraries detected in the project folder, each library object contains the its library folder whose attribute name is folder and it also contains the following metadata information:

• name - name of the library
• version - the version of the library
• author - the author of the library
• maintainer - the maintainer of the library
• sentence - a brief description of the functionality of the library
• paragraph - some feature points about this library.
• url - the website URL of detailed description of the library in Arduino.cc
• architectures - I'm not sure about this metadata.

###Example If we have a library bridge and Esplora in the project folder, then the libraries detector will return the following list:

[Library: (name=Bridge) (version=1.0) (author=Arduino) (maintainer=Arduino <[email protected]>) (sentence=Enables the communication between the Linux processor and the AVR. For Arduino Yún and TRE only.) (paragraph=The Bridge library feature: access to the shared storage, run and manage linux processes, open a remote console, access to the linux file system, including the SD card, enstablish http clients or servers.) (url=http://arduino.cc/en/Reference/YunBridgeLibrary) (architectures=[*]), Library: (name=Esplora) (version=1.0) (author=Arduino) (maintainer=Arduino <[email protected]>) (sentence=Grants easy access to the various sensors and actuators of the Esplora. For Arduino Esplora only.) (paragraph=The sensors available on the board are:2-Axis analog joystick with center push-button,4 push-buttons,microphone, light sensor, temperature sensor, 3-axis accelerometer, 2 TinkerKit input connectors.</br>The actuators available on the board are: bright RGB LED, piezo buzzer, 2 TinkerKit output connectors.)
