/**
* Constructs the list of Proposal Abstract Types. Each entry in the list is a <key, value>
* pair, where the "key" is the unique type code and the "value" is the textual description that
* is viewed by a user. The list is obtained from the Abstract Type database table via the
* "keyValuesService". The intent of this method is to provide a list which is viewed in a GUI. As
* such, the first entry in the list is the generic <"", "select:"> option.
*
* <p>The list is also filtered based upon the abstracts currently in the proposal development
* document. Users are not allowed to create two or more abstracts with the same abstract type.
* Therefore, if an abstract type is already being used, it is removed from the list. If the
* document cannot be found, the entire list is returned (it is not filtered).
*
* @return the list of <key, value> pairs of abstract types. The first entry is always
* <"", "select:">.
