Optimize functions and apply formatting to code

all:
  - code formatting
    - add new lines between blocks of code for readability and overall code consistency
    - add spaces between // and actual comment for readability and overall code consistency
  - remove unused dependency injections
  - extract getSpaceCount into lightweightParse and use it as much as possible

codeFolding:
  - remove obsolete functions

lightweightDOM:
  - comibe createNode and getNode together as those were just delegating the work to each other
  - move cutting current line up to cursor's position from LazyNode constructor to getNode
  - add caching optimization by storing nodes per lines; cache is invalidated every time
    line has been changed; we have to do so to stop GC from bothering us because we create and destroy
    hundred of thousands LazyNode objects that stay unchanged during computations
  - convert node's key and value properties to getKey and getValue getters to become 100% lazy :)
    and improve performance as not every line of code is using those

lightweightParse:
  - improve and optimize almost every single function to gain ~5-10x performance increase

TODO:
  - keep using RAML DOM more and more as it leads to smaller and less repeatable code
