/** findMdpInsert and findCode functions use a similar layout to return the location and contents
2 
  *   .start          => points at the character in the string why the other item starts (ie. comment or code block)
3 
  *   .length         => is the overall length of the comment or code block.
4 
  *   .internalStart  => points at the character in the string where the internal payload starts
5 
  *   .internalLength => is the length of the internal payload
6 
  *   .commandString  => is the command string found within the particular item
7 
  *   .info           => is a structure containing further info about what was found
8 
  * if start is returned as -1 then nothing was found
9 
  *
10 
  * The internalStart/internaLength defines the internal content which will be replaced. This does not include
11 
  * leading and lagging CRLF/LF. So the replacement text is not required to have either leading or lagging line
12 
  * endings. However, if the internalLength is negative this means that leading CRLF or LF must be added by the insertion
13 
  * routine. The reason for this is that it allows insertions between code fences or mdpInsert pairs which have zero lines
14 
  * between them.
