ignore comments

[LiamSkirrow]

There have been some cases where in a comment, the correct syntax is given for a module instantiation:

For example, the following code will be erroneously picked up as a module instantiation:

/*
fragment offset (0)
*/

In this case verilogtree will think there is a module named 'fragment' with instance name 'offset'. Need to ignore anything wrapped in comments -> /* ... */ and // blah

[LiamSkirrow]

The regex strings I use to identify module declarations and module instantiations assume that following the beginning of a newline (^) there is only whitespace before the declaration/instantiation. Therefore, my code already ignores any single-line comment (//).

This ticket only has to watch out for the multi-line comment /* */ over multiple lines.

Nested comments are a bit of a pain to have to deal with, for example:

/* comment
/* another comment

*/
*/

Maybe in the interest of keeping this simple I will just skip multi line comments for now, and just cop it. We ignore single line comments as-is so this is probably good enough for now...

Will move this to the v0.2.0 release instead

Moved back to v0.1.0 since after running verilogtree against some real-world verilog (https://github.com/alexforencich/verilog-i2c) it turns that false-positives are actually very common and need to be dealt with by ignoring multiline comments.
