Added lines 46-63:
Maps (dictionaries) are easy to address -- use the key name. Array sequences (lists) are trickier. The array element at position n (first position is 0) is addressed by "[n]". A wildcard "[*]" indicates any array position.
So
* @@/"a"@@ is @@1@@
* @@/"c"/"e"@@ is 5
* @@/"g"/[1]@@ is 7
* @@/"g"/[*]@@ may be any of 6, 7, or 8
Paths may be relative to the path of an element as well, meaning that the value @@"d"@@ at @@/"c"/"f"@@ may be interpreted as pointing to @@/"c"/"d"@@ with is 5. (Only if you're expecting a JSON path at @@/"c"/"f"@@ though, otherwise it's just the string @@"d"@@ of course.)
Note that the quotations around path elements need to be escaped in JSON strings.
