The shim version of Log#e(String, Throwable).

Parameters
`t`	`Throwable`: the `Throwable` to output.

findCallerClassName

public static String findCallerClassName ()

Finds the external class name that directly called a CLog method.

Returns
`String`	The simple class name (or full-qualified if an error occurs getting a ref to the class) of the external class that called a CLog method, or "Unknown" if the stack trace is empty or only contains CLog class names.

findCallerClassName

Finds the external class name that directly called a CLog method.

Parameters
`t`	`Throwable`: (Optional) the stack trace to search within, exposed for unit testing

Returns
`String`	The simple class name (or full-qualified if an error occurs getting a ref to the class) of the external class that called a CLog method, or "Unknown" if the stack trace is empty or only contains CLog class names.

getClassName

public static String getClassName (int frame)

Return the simple classname from the frameth stack frame in the call path. Note: this method does not check array bounds for the stack trace length.

Parameters
`frame`	`int`: The index of the stack trace frame to inspect for the class name

Returns
`String`	The simple class name (or full-qualified if an error occurs getting a ref to the class) for the given element of the stack trace.
