### 0.5.4
* Added Debug and PartialEq implementations to Index type
### 0.5.3
* Updated index find method to return `Path` references.
* Made `IndexedPath` type and its fields private.
### 0.5.2
* Updated fragment dependency to v0.3.1.
* Properly handle case insensitive indexing
The previous implementation incorrectly modified the path itself when
building case insensitive index entries. This implementation limits case
sensitivity to a discrete search field, leaving the original file path
untouched.
### 0.5.1
* Updated fragment dependency to v0.3.0.
### 0.5.0
* Case sensitivity is now set when populating the index. Converting string
representations to lowercase is expensive; doing it once during index
population (rather than for every subsequent call to find) is considerably
more efficient.
### 0.4.0
* Added the ability to exclude entries using glob patterns when populating index.
* Updated walkdir dependency to v2.0.1.
### 0.3.0
* Add case_insensitive search option
### 0.2.4
* Update fragment dependency to v0.1.2.
### 0.2.3
* Use extracted fragment library for matching.
### 0.2.2
* Use walkdir crate instead of deprecated fs::walk_dir.
### 0.2.1
* Removed deprecated PathExt usage.
### 0.2.0
* Replace similarity algorithm with a space-delimited, term-driven implementation.
