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.
