      NOTE: USE THIS FOR SINGLE CELLS ONLY
      When parsing sheets, all variable names be exact matches when cross-referenceing the metadata and data sections
      However, sometimes people like to put "age (years BP)" in one section, and "age" in the other. This causes problems.
      We're using this regex to match all variableName cells and remove the "(years BP)" where applicable.
