Detailed Description

The console printing class.

The console prints to std::printf or ANDROID_LOG_INFO.

The console class has serveral static methods to print without a class context e.g. System::Console::Print().

An instance of the console class can print three levels:

The information level.
The warning level.
The error level.

Printing a message supports:

A customizable prefix string for each level.
A customizable global prefix string.
Nested sections with customizable indentation width and character.
Suppress printing by setting the current print level.

The output string is: [global prefix]" "[indent string][level prefix]" "[message].
