Two scripts to study the htm module:

- simplecrash.py usually causes a segfault in the htm module
- nocrash.py performs similar actions that do not crash the module

nocrash.py

+"""
+This is a simple test using the htm module. This script
+does not crash.
+
+See simplecrash.py for a similar example that usually does crash.
+"""
+
+import htm
+
+# Look up a trixel on level 7. A level above 6 never seems to crash
+# the module.
+t=htm.lookup(7,39.,131.)
+print(t)
+htm.htm_get_edges(7,t)
+
+# A level of 1 often crashes the module. Some trixels never seem
+# to crash, like this one.
+t=htm.lookup(1,89.,131.)
+htm.htm_get_edges(1,t)
