icd9AddLeadingZeroesShortSingle

<p>This should add leading zeroes when there is definitely no ambiguity,
e.g. V1. However V10 should not be altered, because V010 is a different
code. The goal is for this to be faster, but must be correct! Example in
<code>manip.cpp</code> has the benchmark code.</p>

Calculate comorbidities, Charlson scores, perform fast and accurate
validation, conversion, manipulation, filtering and comparison of ICD-9 and
ICD-10 codes. Common ambiguities and code formats are handled. This
package enables a work flow from raw lists of ICD codes in hospital
billing databases to comorbidities. ICD-9 and ICD-10 comorbidity mappings
from Quan (Deyo and Elixhauser versions), Elixhauser and AHRQ included. This
package replaces 'icd9', which should be uninstalled.
