Knowledge Explorer version 3.6

1. only one input format
As part of my continuing effort to simplify the KR language,
I have eliminated all of the input format options, which were
formerly specified by the ke parameter kformat.  (kformat
is still used internally, but is no longer a parameter.)  The new
ways to specify the different types of input statements are:

    ku -- use "do*" verb and event names with "*" suffix
    cu -- use "do" verb and event names without "*" suffix
    ho -- use "!begin hierarchy" and "!end hierarchy"
    rel -- use "!begin relation relname" and "!end relation relname"

In other words, "do*" denotes an action declaration, and "do"
denotes the occurrence (or instance) of an action.  Event names
with "*" suffix are used to record product/subject/object information.

2. group definitions
The new keyword "of" can be used in defining groups of parts.
For example:

    sequence is group with numerical order
    proposition is sequence of concept

3. space,time,view parameters
The current space,time,view are now ke parameters.  The
current values can be retrieved using questions, e.g.:

    view = ?

The "at" phrase is still used to set space,time,view.
