* Added updateVersion stage as well as some refactoring * Split out into multiple functions * Cleaned up a few failing tests * Added new upgrades to specs * Application specific parameters are prefixed with underscores * Migrated changes back from cesium * Changed 1.1 to 2.0 * Lots of 1.0->2.0 changes in pipeline stages * Tweaks from model generation * Generate default material * Add updateVersion to buildForCesium * Select default scene * A few more small changes * Add removePipelineExtras to cesium build * kmc fixes * Build global cesium include * Update * Update CHANGES.md * Added two more update functions * Update CHANGES.md * Strip version numbers when guessing if invalid * WIP Array-based Traversal * More WIP changes * Removed combineMeshes -> nodes only have a singular mesh now * Operator -> operate * combineNodes, removeUnused and dagToTree traversal changes * More WIP * Bulk WIP changes for traversal * Fixed a few more failing tests * Removed findUsedIds * WIP, switching workspaces * WIP, pretty much just AO left * Fixed a few more tests * All tests pass * Removed riggedSimpleUnoptimized * Delete generateTangentsBitangents models * Don't look for slots in array, just append * Small fixes from testing * More fixes * A few test fixes and byteStride -> bufferView * A few more test fixes * Missed a function * Removed vestigial byteStride references * Some fixes from cesium changes * Fixed cesium dependency list * Fixed some plurality issues * Add KHR_technique_webgl extensions if there are techniques
