Doc::Simply::Assembler - Assemble line and block comments into blocked content

Doc::Simple::Assembler::assembler will iterate through each given comment and do the following:

    1. Combining multiple contiguous lines into a single block
    2. Preserving existing blocks

The result will be a series of blocks, each containing a list of lines.

In addition, it will normalize the content by stripping the first 1 to 2 spaces (if present) and removing a leading '*' (if present).
