LTER_monster2.m
  This m-file will create a  giant (monster) matrix of annual data for LTER ADCPs, 
  Tidbit temp loggers, CTD, VSF, and DFL instruments. The matrix is saved in both 
  (.mat) and (.txt) formats

MONSTER MATRIX

	(1)		Matlab serial time  (GMT)			n/a
	(2)		Year							ADCP 
	(3)		Month							ADCP 
	(4)		Day							ADCP 
	(5)		Decimal Time					ADCP 
	(6:21)	East Velocity  2m-17m bins			ADCP 
	(22:37)	North Velocity 2m-17m bins			ADCP 
	(38:53)	Mean Beam Intensity 2m-17m bins		ADCP 
		Note: Carpenteria uses half meter 2m-9.5m bins

	(85)        VSF, 150 degrees					VSF
      (86)        Nitrate						Nitrate sampler

  The required files in the root directory are:
     LTER_monster2.m
     load_ADCP.m
     tidbit_filter.m
	getdatayear.m

  LTER_monster2 is a function. Its input arguments are the site location and year 
  for which you want to make a monster file. It needs to know which data files 
  correspond to the desired location and year, so it looks for a log file. These 
  log files are located in the data directory with the actual data files. .ssv files 
  for tidbits, .mat files for ADCP data, .txt files for CVD data.

  The ADCP data is pre-processed with WinADCP to create a .mat file of desired
  variables. load_ADCP.m then creates a structured array of desired variables 
  that are imported by this m-file.  ADCP data are filtered and then interpolated 
  onto a 20 min time interval.  This m-file then imports desired Tidbit files 
  using the function tidbit_filter.m which yields filtered time and temp vectors.  
  These are then interpolated onto the 20 min time interval.  Next the .txt files 
  output from ctd_vsf_dfl_process2.m are interpolated onto the matrix. Finally the
  .txt files from the nitrate sampler are interpolated into the monster matrix.
