Detailed Description

A smart class to hold the text for parsing.

A variable of this class can hold not only the text of the ARTS Control file, but also a position in the text. This is handy for parsing. There is also a function to return the current character and functions to advance the position. (AdvanceChar advances the position to the next character, doing a line break if necessary; AdvanceLine goes to the next line.)

mLine and mColumn are 0 based, but Line and Column are 1 based.
