Library "CommonFunctions"
This Library provides some handy functions commonly used in Pine Script.

crosses(source1, offset1, source2, offset2) Checks the existance of crosses between the series
  Parameters:
    source1: First series
    offset1: (Optional) Offset of First series. By default 0
    source2: (Optional) Second series. By default 'close' price
    offset2: (Optional) Offset of Second series. By default 0
  Returns: [cross, crossOver, crossUnder]

marketState(source1, offset1, source2, offset2) Determines Bullish/Bearish state according to the relative position between the series.
  Parameters:
    source1: Active series used to determine bullish/bearish states.
    offset1: (Optional) Offset of First series. By default 0.
    source2: (Optional) Second series. By default 'close' price.
    offset2: (Optional) Offset of Second series. By default 0.
  Returns: [bullish, bearish]

histProfile(source) Histogram profiling
  Parameters:
    source: Histogram series
  Returns: [histPosUp, histPosDown, histNegUp, histNegDown]

srcSelect(showSrc1, src1, showSrc2, src2) Selects the appropiate source. If multiple sources are activated simultaneously, the order within the switch clause prevails. The first one activated is the one being output.
  Parameters:
    showSrc1: Boolean controlling the activation of Source #1.
    src1: Source #1.
    showSrc2: Boolean controlling the activation of Sources #2-10. By default 'false'.
    src2: Sources #2-10. By default 'number'.
