Accept comment-only expressions

First of all I would like to thank you for the great calculator.
I use it regullary my friends and colleagues too.

In the practice i found the following problem
1. Some thimes in long calculation lists some thimes is difficult to go
back in the history and remember why some calcultions are done
2. In exchanging between different users the files with calculations some
times is needed to put some text between the calculations in order to
comment why some of them are done and to clarify the purpose of the such
documents.
3. In such cases the comments may be written in some text files and such
files may be delivered together with the saved history files but it is
annoing and not very handy. It is clear that we need some way to put
comments in between the calculations. This is the way many engineers are
working and it is the appropriate way of doing technical calculations. 


This is my proposal for enhancement.

Please make possible some line of text and nmbers to be inserted in the
input field of Speedcrunch but make it excluded from the parsing and
evaluation. This line should appear in the histry list and also in the
saved file with the calculations
1. You could make available a button annotated as 'Text' or maybe
'Comment' or may be some keyboard command for this purpose.
2. When one writes some comment in the input field of Speedcrunch He/She
should press this button. And then Speedcrunch instead to generate a ERROR
message should exclude this comment from parsing and evaluation but put it
as a new line in the history and in the saved file.
3. When batch calculations will be used such lines should not be used in
the calculation proces but stay in the listings (some how like the
comments lines in the source code files)
