Remove typo from sequential processing
Add YEAR in to names.merge key and join

make sure the NEWEST names are used for schools that change names, as
happened in Washington.
Change search for coeff matrices to deal with non-existent BASELINE or COHORT matrices

For heterogeneous content area projections (EOCT).  Example in Georgia
where there are BASELINE mathematics matrices, but not for Coordinate
Algebra.  Here we set it up to use the 2013 (current year) cohort ref’d
matrices as an analog to baseline.

Pretty up warning messages for mixed coef matrices
Add test.projection.iter function to select ONLY "official" course progression related configurations
Add YEAR_WITHIN checks to getPanelData / Vnames.  Also change selection/formation of YEAR in straight projections.

Had to add YEAR_WITHIN for Georgia.  The YEAR issue came up with EOCT
Lit subjects where we use two priors from the same year/grade.  Need to
use the yearIncrement function rather than just taking the head/tail of
the sgp.panel.years
Fix the test.projection.iter function so that it takes only a single (full canonical) projection iteration.  Then force sgp.exact.grade.progression to FALSE
Merge branch 'master' of github.com:CenterForAssessment/SGP
Fix if/else setup
Merge branch 'master' of github.com:CenterForAssessment/SGP
Add sgp.data.names argument to all calls to getPanelDataVnames for projections
Allow for some matrices to be NULL in get.grade.projection.sequence.matrices, then remove NULL elements from list

Needed in Georgia EOCT Lit.  Without sgp.exact.grade.progression = TRUE
need to filter out missing matrices with either (but not both) ELA or
READING in the grade progression.
Fix bug in getPanelData for lagged projections
Change order of test of equality to avoid warnings.
Fix bug in selection year_lags.projection.sequence indexing - caused selection of wrong matrices
Add in ACHIEVEMENT_LEVEL for lagged projections data and fix name for YEAR_WITHIN
fix index bug
get rid of warnings in test.projection.iter

sample warnings (to be expected given test):
2: In sgp.iter[["sgp.content.areas"]] ==
tmp.content_area.projection.sequence :
  longer object length is not a multiple of shorter object length
3: In sgp.iter[["sgp.grade.sequences"]] ==
tmp.grade.projection.sequence :
  longer object length is not a multiple of shorter object length
