What is claimed is: 1. A crystalline graphitic nanofiber consisting essentially of at least one uninterrupted, unbroken, substantially graphite sheet that is aligned substantially parallel to the longitudinal axis of the nanofiber and which has a substantially non-cylindrical multifaceted tubular structure, wherein when two or more of said sheets is present they are present as a tube within a tube structure and wherein the distance between graphite sheets is from about 0.335 nm to about 0.67 nm, wherein said substantially crystalline graphitic nanofiber has a crystallinity greater than about 95%. 2. The nanofiber of the claim 1 wherein the distance between the graphite sheets is from about 0.335 and 0.40 nm. 3. The nanofiber of claim 1 wherein at least a portion of the edge regions of the nanofiber contain a functional group selected from the group consisting of basic groups, acidic groups, and oxygenated groups. 4. The nanofiber of claim 3 wherein the functional group is a basic group that is a NH4+ group. 5. The nanofiber of claim 3 wherein the functional group is an acid group which is a COOH- group. 6. The nanofiber of claim 3 wherein the functional group is an oxygenated group selected from the group consisting of hydroxyl, peroxide, ether, keto, and aldehyde.
