incorrect code for nbTextWithCode with multiline string on same line as command

[pietroppeter]

Compiling and running this file:

import nimib
nbInit
nbTextWithCode: """problem
solution"""
echo "nb.blk.code: ", nb.blk.code

last line of output is (when using CodeAsInSource now default):

nb.blk.code: """problem

while it should be (as it is when using -d:nimibCodeFromAst)

nb.blk.code: """problem
solution"""

fix to be done in code in src/nimib/sources.nim

In addition to this I think this also breaks:

nbCode: someTemplate:
  code block

so the problem in general is multi-line blocks that start on the same line as the command

Here's a preliminary plan for how to determine the form of the code:

• startLine == endLine and lines[startLine].isCommandLine, it is either a single line expression or it contains a multiline-string
  • lines[startLine].count("\"\"\"") mod 2 == 0, it is a single line expression as the number of opening and closing strings match.
  • else, it ends with a multiline string
• elif startLine == endLine, it starts on a new line and could contain either a single line expression or a multiline string. same checks as above.
• else, it is a multiline expression which might or might not end with a multiline string

All branches share a lot of code so I'll try and come up with a way of splitting the logic into reusable functions more.
