Useful for finding constants in a string like true, false, etc.
returns the current character without changing the IO pointer or index.
Used to find strings and their ilk Finds the next non-escaped char
ch -   character to findesc -  escape character to avoid next char if escapedChecks to see if there is a next character.
This is mostly for debugging and testing.
returns the next character moving the file pointer or index to the next location.
Reads a number from the character source.
Combines the operations of nextChar and hasChar. Characters is -1 if not found which signifies end of file. This might be preferable to avoid two method calls.
Skip white space.
