ESAAcuity initialize method adds a boolean imposeNames, which requires that the names of the acuities fall within majors, minors and resus.
ESAAcuity other.acuities method allows the user to specify whether it is an acuity-based model or not, through the acuityModel flag. If acuityModel is FALSE, then this method will return NULL.
ESAEDAggregated initialize method adds an additional argument, otherFlags. This allows for the inclusion of variables that were derived seperately and externally to those in ESAEDPatientLevel. For example, a variable which is the product of two or more columns.
ESAEDAggregated now accounts for whether a specific acuity model is run, and thus henceforth whether to include the other acuities in the model (e.g. majors and resus when looking at minors crowding)
marginaleffects, odbc, and DBI packages have been moved to 'suggests'.
