ezec version 1.0.0

NEW FEATURES

• results returned as a tbl_df from the dplyr package.
• The data frame produced via EC_table()gains a column defining the sample
  names instead of using the "rownames" attribute (This was addressed in part
  for #3). This is considered a
  breaking change.

BUG FIX

• samples with insufficient data no longer throw an error when running
  EC_table() without three response levels
• Vignette is no longer titled "Vignette Title"
